Mike Rowe has taken on some really nasty jobs during the fourth season of Dirty Jobs, but tonight might be his worst job yet. Mike will be heading to the Villard Ranch in Craig, Colorado.

At the Village Ranch, Mike will work with modern day sheepherders. His tasks will include shearing, tagging, worming and castrating young sheep. In addition to sheep castration, Mike will also be taking on a concrete wall.

Mike will travel to an automobile dealership in Orange County, California, where he will attempt to saw down a giant concrete wall. The wall has to come down to make room for a new wash bay. In order to take down the wall, Mike will be using a special saw with blades made of diamonds. Unlike Mike’s first job for this week, his second task with the diamond saw actually sounds like a lot of fun.
